Environment (micronaut 3.8.1 API)

All Superinterfaces:

AutoCloseable, Closeable, ConversionService<Environment>, LifeCycle<Environment>, PropertyResolver, ResourceLoader, ValueResolver<String>

All Known Implementing Classes:

DefaultEnvironment
```
public interface Environment
extends PropertyResolver, LifeCycle<Environment>, ConversionService<Environment>, ResourceLoader
```
The current application environment. The environment represents the loaded configuration of the application for a current list of active environment names.

The active environment names can be obtained from the getActiveNames() method and are established from one of the following sources:
- Environment names passed to the ApplicationContext.run(String...) method
- The value of the ENVIRONMENTS_PROPERTY system property
- The value of the ENVIRONMENTS_ENV environment variable
- The class that started the application
When establishing the environment name from the class the started the application Micronaut will inspect the stacktrace. If JUnit or Spock are featured in the stacktrace the TEST environment is included. When running from Android the ANDROID environment is included.
